A passenger plane has flipped upon arrival at Toronto’s Pearson International Airport and ended up on its roof, injuring 19 people, including at least one child.

The airport confirmed on X that an “incident” occurred on Monday (local time) with the Delta Airlines flight from Minneapolis and that all passengers and crew were accounted for.

Video from the scene showed the Mitsubishi CRJ-900LR, which had been operated by Delta subsidiary Endeavour Air, upside down on the snowy tarmac as emergency workers hosed it down.

“We just landed. Our plane crashed. It’s upside-down,” John Nelson, who took the video, said as he walked away from the plane.

“Firefighters on site. Most people are going to be OK. We’re all getting off.”

He noted that “most people appear to be OK” and that passengers were getting off the plane.

Ornge air ambulance said it transported a child to Toronto’s SickKids Hospital and two adults with critical injuries to other hospitals in the city.

“Emergency teams are responding,” the airport said in a post on the social platform X.

“All passengers and crew are accounted for.”

In a later update, airport boss Deborah Flint said none of those injured were in a critical condition.

“There was no loss of life and this is indeed in part due to our heroic and trained professionals, our first responders at the airport,” she said.

“This is exactly what our emergency, operations and first-responder partners are all practised and trained for. Again, this outcome is in due part to their heroic work and I thank them profusely. Our thoughts and prayers are with all.”

Flint said it had been a “textbook response” from emergency services, who were at the landing site within minutes.

She said the airport halted operations on all five of its runways in the aftermath of the crash. Flights had since resumed on all but two of them.

“The other runways are remaining to serve the investigation, which will be carrying forward for the rest of tonight and into the next several days. These two runways will remain closed while our investigation takes place,” she said.

The plane was carrying 76 passengers and four crew. Among those on board, 22 were Canadians while the remainder were other nationalities that have not been detailed.

In the aftermath, the grounded plane was partly obscured by snow from a winter storm that hit Toronto, capital of the Canadian province of Ontario, at the weekend.

The Meteorological Service of Canada said the airport was experiencing blowing snow and winds of 50km/h, gusting to 65km/h.

The temperature was about -8.6 degrees.

In an audio recording from the tower, air traffic control warns the pilots of a possible air flow bump in the plane’s glide path because of an aircraft in front of it.

“It’s very rare to see something like this,” said John Cox, CEO of aviation safety consulting firm Safety Operating Systems in St Petersburg, Florida.

“We’ve seen a couple of cases of take-offs where airplanes have ended up inverted, but it’s pretty rare.

“The weather conditions were windy … But the airplanes are designed and certified to handle that. The pilots are trained and experienced to handle that.”

The US Federal Aviation Administration said the Transportation Safety Board of Canada would lead the investigation and provide updates.

The National Transportation Safety Board said it was leading a team of US investigators to assist in the Canadian investigation.

It is at least the fourth major aviation mishap in North America in the past month.

A commercial plane and an army helicopter collided near Washington DC on January 29, killing 67 people, a medical transport plane crashed in Philadelphia on January 31, killing the six people on board and another person on the ground, and 10 were killed in a plane crash in Alaska.

Delta said it was “aware of reports of Endeavour Flight 4819 operating from Minneapolis-St Paul to Toronto-Pearson International Airport as involved in an incident”.

Minneapolis-based Endeavour Air is the world’s largest operator of CRJ-900 aircraft. It operates 130 regional jets on 700 daily flights to more than 126 cities in the US, Canada and the Caribbean.

The CRJ900, a popular regional jet, was developed by Canadian aerospace company Bombardier.

It is in the same family of aircraft as the CRJ700, the type of plane involved in the midair collision in Washington DC on January 29.
